B2B Procurement FAQ: Product Comparisons & After-Sales Service
> Q1: What is the main advantage of the C9300-24P-A over the C9300-24P-E?
A: The key difference is the software tier. The C9300-24P-A comes with the Network Advantage license, which unlocks full Layer 3 enterprise routing features such as BGP, Advanced EIGRP, VRF-Lite, EVPN-VXLAN, and Cisco TrustSec segmentation. The C9300-24P-E runs Network Essentials, which only covers basic routing protocols (Static, OSPF, RIP) and is limited to fewer virtual networks.
> Q2: How many PoE+ devices can the Cisco C9300-24P-A power simultaneously?
A: With its default PWR-C1-715WAC-P power supply, the switch delivers a 445W PoE budget. This allows it to support up to 14 ports of full PoE+ (30W per port) or all 24 ports of standard PoE (15.4W per port). For full 30W PoE+ across all 24 ports simultaneously, you can upgrade the power supply configuration or add a secondary redundant power module into the slot.
> Q3: Can I use 10G and 25G optical transceivers on the C9300-24P-A?
A: Yes. Because this switch utilizes a modular network module architecture, you can upgrade its uplink speeds by inserting modules like the C9300-NM-8X (for 8 x 10G SFP+ links) or the C9300-NM-2Y (for 2 x 25G SFP28 links). These slots are fully compatible with enterprise optical transceivers and direct attach copper (DAC) breakout cables.
> Q4: What type of warranty and RMA support is included with this switch?
A: Every Cisco Catalyst C9300-24P-A supplied through our desk includes the official Cisco Enhanced Limited Lifetime Warranty (E-LLW). This contract features Next-Business-Day (NBD) hardware replacement delivery (where logistically available) and 90 days of 8x5 Cisco Technical Assistance Center (TAC) software validation support. For critical data centers, optional 24/7/365 Cisco Smart Net Total Care (SmartNet) coverage can be added.
> Q5: Can the Catalyst C9300-24P-A be stacked with legacy Catalyst 3850 or 9200 switches?
A: No. The C9300-24P-A uses StackWise-480 technology with specific architectural timing architectures. It can only be stacked with other models within the Cisco Catalyst 9300 Series. It cannot stack vertically with the Catalyst 9200 series (which uses StackWise-160) or legacy Catalyst 3850 hardware fabrics.
